This relies heavily in infrastructure taken from the v3d driver. We should
probably look for ways to share the code between both drivers by creating
a surface layout library that we can use from both, or at least moving
parts of the v3d driver to broadcom/common. Specifically:
We take v3d_tiling.c, which requires gallium's pipe_box type for some
helper functions that we don't quite need yet.
We copied and adapted bits of v3d_resource.c into v3dv_image.c, however,
it should be possible to look for ways to reuse the code instead of
duplicating it.
Pre-compute UIF padding into the slice setup. This is different from
what we do in v3d (we do this at cerate_surface time), but it is
more convenient for us to pre-calculate it here for all mipmap
slices.
